PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 223,751, dated January 20, 1880.

l Application filctl December 9, 1879.

To all whom it may concern Be it known that I, JAMEs OLIVER, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Plow-Points; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in plow-points, the object being to provide a plow-point with ,a renewable nose, the construction of parts being such that the detachable nose may be readily secured to the nose portion of the plow-point, and secured against either lateral or vertical displacement by means of a single fasteningbolt, but a single joint being formed on the wearingface of the plow-point between the body of the latter and the renewable nose; and to this end my invention consists in a plow-point with a plain flat seat formed on its nose portion and a shoulder on its rear end with outwardly-flaring ends, the end of the nose portion having a square flat shoulder, and the under side thereof formed with a beveled recess and a recess for a bolt and nut, in combination with a removable nose adapted to fit upon the plain flat seat on the nose portion of the plow-point, and its end fitted snugly againstthe rear shoulder or wall, while the lower portion of the nose is provided with a shoulder which seats against the square fiat shoulder on the end of the nose portion of the point and is provided with a lip or tongue that fits the beveled recess of the nose, the parts being secured together by means of a bolt and nut, the latter being located in a recess formed on the under side of the plow-point.

In the accompanying drawings, Figure 1. is a view, in perspective, of a plow-point embodying my improvement. Fig. 2 is a similar view of the under side of the plow-point. Fig. 3 is a view, in perspective, of the plow-point with the nose removed therefrom. Fig. 4 is a similar view, showing the under side of the plow-point. Fig. 5 is a view, in perspective, of the under side of the removable or slip nose.

A represents the plow-poin t, having a plain fiat seat, B, formed on its nose portion, the forward end of the seat terminating in a fiat square shoulder, 0, while the rear end terminates in a shoulder, D, having outwardlyflaring ends a a. v

The under side of the nose portion of the plow-point is provided with a beveled recess, E, which extends rearwardly a short distance from the shoulder 0, while in rear of the recess E is formed a recess, F, and through the latter portion of the plow-point is formed a bolt-hole, G.

The removable nose H is constructed with a portion, I, which fits upon the seat B, the rear edge of said overlapping portion having its corners cut away or beveled oft", as at I) b, to correspond with the beveled or flaring portions to a of the shoulder D, so that when the nose is secured in place its rear end shall be prevented from moving laterally in either direction.

On the under side of the removable nose is formed a square shoulder, K, which fits snugly against the flat square shoulder O on the plowpoint. A beveled lip or tongue, L, projects rearwardly from the shoulder K, and fits within the beveled recess E in the plow-point, whereby the removable plow-point is furnished with a firm seat near its point to sustain the endwise strain brought against it in use, and, also,

its forward end is prevented from lateral displacement in either direction by means of the beveled lip or tongue L and recess E.

The reir ovable nose is perforated near its upper end, at M, the opening being preferably countersunk for the reception of the bolt-head N of the bolt N, which latter extends through the bolt-hole G in the plow-point and has a nut, O, secured to the threaded end of the bolt, said nut being located within the recess E, and thereby prevented from being loosened or lost while the plow is in use.

It will be observed that the removable nose is furnished with an extended flat bearing on the nose portion of the plow-point, and all longitudinal joints between the nose and plowpoint are obviated, the removable nose being equal in width to the nose portion of the plowpoint.

The detachable nose is most firmly secured under side of the nose in the same horizontal plane with the under side of the edge of the plow-point.

A plow-point'embodying my invention comprises great strength and durability and neatness of form, and is susceptible of being highly finished, and also enables the point to be readily renewed when \vorn.

The plow-point and removable nose may have chilled surfaces imparted to any part thereof, as may be desired.

I am aware that many different constructions of plow-points with removable or renewable nose-pieces have heretofore been produced, and hence I would have it understood that I make no broad claim to a plow-point provided with a renewable or slip nose-piece, as my invention consists in the peculiar construction and combination of parts set forth in v the specification and pointed out in the claims.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a plow-point provided with a plain seat having beveled shoulders on its rear edge, a square shoulder on its forward edge, and a beveled recess on its under side, of a removable plow-point, the upper portion of which is provided with beveled corners at its end, a square shoulder, and a beveled tongue or lip, substantially as set forth.

2. The combination, with a plow-point provided with a plain flat seat on its nose portion, said seat having beveled shoulders on its rear edge and a square shoulder on its forward edge and a beveled recess on its under side, of a removable plow-point, the upper portion of which is provided with beveled corners at its end, a square shoulder, and a beveled tongue or lip, and a fastening-bolt extending through the plow-point and rear portion of the removable nose, the fastening-nut being located in a recess on the under side of the plowpoint, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of December, 1879. JAMES OLIVER.
